Overview
The ZF 2093.110.037 P.T.O. SHAFT is a critical power take-off component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission’s internal gearing to auxiliary hydraulic pumps or driven equipment. Positioned within the rear housing of the gearbox, the shaft interfaces directly with the differential assembly and bearing supports to ensure seamless torque delivery. The SKU 2093.110.037 is precision-machined to ZF’s factory tolerances, guaranteeing a direct fit without modification. When paired with a DIFFERENTIAL or a TAPER ROLLER BEARING, this shaft maintains proper gear alignment and reduces parasitic power loss.
Symptoms of Failure
- Oil Leaks at the PTO Housing: Worn splines or a cracked shaft surface can allow transmission fluid to seep past the seal, leaving puddles under the vehicle.
- Gear Slipping Under Load: When the shaft’s engagement teeth become rounded, the PTO may disengage intermittently during operation, causing a sudden loss of hydraulic power.
- Excessive Vibration or Whining Noise: A bent or fatigued 2093.110.037 shaft creates harmonic vibrations that resonate through the driveline, often accompanied by a high-pitched whine at idle.
- Difficulty Engaging the PTO: Binding or galling on the shaft’s outer diameter prevents smooth sliding engagement, requiring excessive force to activate the power take-off.

Compatibility
This P.T.O. shaft is designed exclusively for ZF’s WG-series modular transmissions. It directly fits the WG100, WG130, and WG131 models. The same shaft geometry is also shared with the WG180 and WG200 variants when used with a compatible DIFFERENTIAL housing. For installations requiring a reinforced carrier, the DIFF.HOUSING provides the necessary structural support. Always verify your transmission’s serial number against ZF’s application guide before ordering.

Frequently Asked Questions
Q: Can the 2093.110.037 shaft be used in a ZF WG180 transmission?
A: Yes, the shaft is physically compatible with WG180 and WG200 models, provided the PTO housing and differential carrier are from the same series. Always cross-reference your housing part number with the DIFF.HOUSING specifications.
Q: What causes premature wear on this P.T.O. shaft?
A: The most common cause is insufficient lubrication due to a clogged oil passage or a failing TAPER ROLLER BEARING. Contaminated fluid with metal debris also accelerates spline wear.
Q: Do I need to replace the thrust washer when installing a new shaft?
A: It is strongly recommended. The THRUST WASHER (0730300820) and the THRUST WASHER (5838300811) are sacrificial components that set the correct end-play for the shaft. Reusing worn washers can lead to immediate gear clash.
